自2018年首个免疫检查点抑制剂获批治疗非小细胞肺癌(NSCLC)以来,国内陆续有多个程序性死亡受体1(programmed death 1,PD-1)及程序性死亡配体1(programmed death ligand 1,PD-L1)的抗体药物获批用于NSCLC。不同药物及适应证对PD-L1表达提出了不同的检测需求,包括伴随诊断、补充诊断或不需要检测等。同时,对应的PD-L1检测试剂克隆号也有所增加。2020年国内发布的NSCLC PD-L1表达检测共识对此已经进行充分说明或论述[1, 2],本共识就上版共识之后新上市的临床药物适应证、PD-L1检测适用人群变化及检测试剂方面的进展或研究数据进行梳理。共识编写组基于更新的循证医学证据及新增的中国临床实践需求,形成更新版共识拟解决的问题框架;随后以问题为导向广泛收集近3年国内外发表的高质量文献数据,形成更新点推荐;随后组织多学科专家通过共识会议法,针对更新点进行1轮投票及修改意见收集,根据收集的投票结果及反馈意见,修改及完善后组织第2轮投票;最终形成了本共识8个更新点推荐,推荐等级以证据强度为主,证据级别不足时参考专家投票意见。
3.SP263及其他新型PD-L1克隆号检测试剂:尽管克隆号SP263作为伴随诊断试剂参与IMpower010临床试验,但尚未就此适应证获得NMPA批准为伴随诊断。因此,国内临床使用时暂不能作为优先推荐。另外,包括克隆号QR1、JS311等[12, 13],其中克隆号JS311是专门用于指导特瑞普利单抗应用的新型PD-L1免疫组织化学抗体,但鉴于该类少见抗体克隆号相关的研究报道有限,且面临抗体可及性、不同条件实验室开发检测(laboratory developed test,LDT)性能评估等问题,尚不满足临床应用条件,目前不推荐临床使用。
